Source: Simon Fraser University New research adds weight to the argument that prolonged sitting can be dangerous to your health. An international study of more than 100,000 people in 21 countries found that people who sat for six to eight hours a day had a 12-13% increased risk of premature death and heart disease, while those who sat for more than eight hours a day increased to a creepy 20 percent. The study, led by Simon Fraser University Health Sciences professor Scott Lear and Wei Li of the Chinese Academy of Medical Sciences in Beijing, is published today in the journal JAMA Cardiology. Their study followed an average of 11-year-olds and found that long sitting time was associated with an increased risk of premature death and cardiovascular disease. While sitting was problematic in all countries, it was particularly problematic in low- and lower-middle-income countries. “The dominant message here is to minimize how long you sit,” says Lear. “If you have to sit, most exercise at other times of the day will offset this risk.” Unsurprisingly, those who sat more and were less active had the highest risk – up to 50 percent – while those who sat more but were more active had a significantly lower risk of about 17 percent. Unsurprisingly, those who sat more and were less active had the highest risk – up to 50 percent – while those who sat more but were more active had a significantly lower risk of about 17 percent. The image is public domain “For those who sit for more than four hours a day, replacing a half-hour seat with exercise has reduced the risk by two percent,” notes Lear. “With only one in four Canadians meeting activity guidelines, there is a real opportunity for people here to increase their activity and reduce their chances of dying prematurely and suffering from heart disease.” The study found a specific correlation in lower-income countries, leading researchers to speculate that it may be due to the fact that living in higher-income countries is usually associated with higher socioeconomic status and better-paying jobs. Clinicians need to focus on less sitting and more activity, as it is a low-cost intervention that can have huge benefits, Lear notes. But while clinicians need to get the message across about the active seat, people need to better assess their lifestyle and take their health seriously, Lear adds. “Our study found that the combination of sitting and inactivity accounted for 8.8 percent of all deaths, which is close to the contribution of smoking” (10.6 percent in the Lear and Li study). “It’s a global problem that has an extremely simple solution. “Scheduling time to get up from this chair is a good start.”

JAMA Cardiology Abstract Association of sedentary living time with mortality and cardiovascular events in high-income, middle-income and low-income countries Significance
High seating times are associated with increased risk of cardiovascular disease (CVD) and mortality in high-income countries, but it is unknown whether the risks also increase in low- and middle-income countries. Purpose
Investigating the correlation of sitting time with mortality and major cardiovascular disease in countries at different economic levels using data from the Perspective Urban Epidemiology study. Planning, Setup and Participants
See also This population-based cohort study included participants aged 35 to 70 years recruited from 1 January 2003 and followed until 31 August 2021 in 21 high, middle and low income countries with a median follow-up of 11.1 years. Exhibitions
Daily sitting time was measured using the International Physical Activity Questionnaire. Main Results and Measures
The composition of all-cause mortality and major cardiovascular disease (defined as cardiovascular death, myocardial infarction, stroke, or heart failure). Results
Of the 105,677 participants, 61,925 (58.6%) were women and the mean age (SD) was 50.4 (9.6) years. During an average follow-up of 11.1 (IQR, 8.6-12.2) years, 6233 deaths and 5696 major cardiovascular events were documented (2349 myocardial infarction, 2966 stroke, 671 heart failure and 1792 cardiovascular death). Compared to the control group (<4 hours per day sitting position), higher sitting time (≥8 hours per day) was associated with increased risk for the combined effect (risk ratio [HR]1.19; 95% CI, 1.11-1.28; Pfor voltage <0.001), mortality from all causes (HR, 1.20; 95% CI, 1.10-1.31; Pfor voltage <0.001) and major CVD (HR, 1.21; 95% CI, 1 , 10-1,34; Pfor trend When stratified based on the country’s income levels, the correlation of seating time with the combined effect was stronger in low-income and lower-middle-income countries (≥8 hours per day: HR, 1.29, 95% CI, 1.16 -1.44) compared to high and upper middle income countries (HR, 1.08; 95% CI, 0.98-1.19, P for interaction = 0.02). Compared with those who reported sitting less than 4 hours a day and a high level of physical activity, participants who sat for 8 or more hours a day had a 17% to 50% higher associated risk for the combined outcome at all levels of physical activity. . and the risk was mitigated along with increased levels of physical activity. Conclusions and Relevance High seating times have been associated with an increased risk of all-cause mortality and cardiovascular disease in economically diverse environments, especially in low- and lower-middle-income countries. Reducing sedentary lifestyles along with increasing physical activity can be an important strategy in relieving the global burden of premature death and cardiovascular disease.
